Ok tell you what, if that coyote can dig under(which he is very capable of doing) put you up a small piece of electric wire and do that and it will shock the bajeebers out of him. Or I know this is cruel( I usually like to end an animals life very quickly and less painful to the animal as possible but you have to do what you have to do) but soak a hot dog in antifreeze overnight and put it in a small panty hose in a tree. But please only do this if you are desperate. Don't do it just to try and get rid of him. Anyways good luck with everything and I hope you can get rid of him. Dead or alive. thanks Dusty
